From the official start of adulthood at 18 until the end of the 20s, most men without an existing medical condition from childhood tend to be in the prime of their health. Even after physical and recreational stress on the body, recovery for men between 18-29 tends to be fast.

Despite generally good health in most men in their late teens and twenties, medical problems can start brewing. For some men, this is the time when problems such as diabetes and abnormal lipid and cholesterol levels might pop up - issues that can often be identified with the A1c test and the lipid panel. Other wellness markers such as the CBC and comprehensive metabolic panel are also helpful in establishing a wellness baseline and screen for liver, kidney, and immune dysfunction.
